Once you download and run the utility, it will scan for out-of-date or missing drivers:. When the scan is complete, the driver update utility will display a results page showing which drivers are missing or out-of-date:.
Many computer problems are caused by missing or outdated device drivers, especially in Windows If your desktop or laptop is running slow, or keeps crashing or hanging, there is a good chance that updating your drivers will fix the problem. Unlocks new features and configuration options in your devices, especially with video cards and gaming devices.
The Windows 7 and Windows 10 audio subsystems use similar algorithms to determine the default audio endpoint when no user preference has been specified.
However, the Windows 10 algorithm is different from Windows 7 in the way that it handles user selection of the default and that it handles a per-application preference. This topic describes how the default audio endpoint is selected in Windows For a better understanding of what is new to Windows 10, default audio endpoint selection in Windows 7 is also explained. The Windows 7 and Windows 10 audio subsystems use a similar algorithm to determine the default audio endpoint.
The algorithm operates as follows:. The audio subsystem considers only ACTIVE endpoints in the present and enabled state when it determines the default audio endpoint. Any events that cause an endpoint’s state to change from or to the ACTIVE state can potentially affect the current default audio endpoint.
Such events include inserting an audio device, unplugging a device, and installing a new audio device. In response to such operations, the Windows audio subsystem runs the default audio endpoint heuristic algorithm to determine the new default audio endpoint.
The endpoint timestamp property is a property key containing the system time. In Windows 7, an endpoint’s timestamp property is created or updated when it is set as the default audio endpoint through the Control Panel Sound application. A timestamp property is associated to each role, and the timestamp property is used by the default selection algorithm to identify which endpoints have been set as the preferred default by the user for that role.
The algorithm will identify the endpoint with the newest timestamp property as the default endpoint. The timestamp property that was used in Windows 7 for the user default preference did not allow for automatic selection of a newly attached device after the initial default selection. For example, if a user set the internal speaker as the default endpoint at any time in the past and later attached new USB headphones, the system would never move to the USB headphones without a manual selection.
Starting in Windows 10, user default selection is built as a tree-like structure of past preferences which considers what endpoints were available at the time of the default selection done by the user. The reason for this is that when a user selects a default endpoint, they are communicating their preference for that endpoint relative to what other endpoints were active at the time of the selection.
The user is not communicating an absolute preference for the selected device forever and in all situations. Use and creation of the Timestamp Property has been removed from Windows 10, replaced by the Level property.
The level property is used to build the tree-like structure of user preferences. Like the timestamp property, there is a level property associated to each role. The level property is created or updated any time the user selects a default endpoint though the sound control panel, the sound settings page, or the audio control in the system tray.
When an endpoint is selected as a default, that endpoint is moved to the top of the tree-like structure by assigning it the highest available level. The next level down in the tree would contain one or more endpoints which either have been selected in the past as a default, or were active at the time of this selection but have never been selected by the user. Each subsequent selection brings the desired endpoint to the top of the list, moving prior selections down and grouping active, but as yet unselected, endpoints together to create tie conditions.
In the event that all endpoints in the system are set as a default, the resulting structure becomes a simple ordered list with one endpoint at each level. First, active endpoints without a level value are rank compared, with the endpoint with the highest rank selected to be default. This way endpoints which have been recently added are given a first opportunity to be the default because they are the newest in the system and connected after the user selected the previous default.
Next, if all active endpoints contain a level, then the endpoint with the highest level, without a tie, is chosen as the default. Having the highest level indicates that at some point in the past the user has set this endpoint as the default while the other endpoints, with a lower level value, were active.
Finally, if all endpoints contain a level value, and the endpoints with the highest level values are all tied, the endpoint rank is then used to break the tie. Please be aware that this scan might take a while, so please be patient while it is working.
